This Useful Information chart is on the inside back cover of a graph paper composition notebook. The cover is not the typical marble design. Right away I see some cool icons and graphics…the other Useful Information charts 1-3 have only text. Also, this one has a 3-inch ruler! The content is much the same as chart 2.

an acre measures ~209 feet on each side

A perch of stone is 16 1/2 feet long, by 1 1/2 feet wide, by 1 foot high. (I would call this a low wall, but what do I know?)

This product is made for 3rd graders (for some reason), so presumably the Useful Information will be especially useful for 8-year-olds. I am hoping that it will list the number of marbles that can fit into a pocket (29); the average weight of a frog (depends: if it is the pee pee kind, then really light weight); or number of pices of gum that can be jammed into a mouth (no upper limit).

This is the inside back cover of the composition book. There is another Useful Information chart on the outside cover of this notebook, with different information. It appears as if it was written by a different author.

This chart is on the outside back cover. What is interesting is that the book has another Useful Information chart on the inside back cover, just in case one wasn’t enough. I would guess that about 90% of the information is the same in both charts, though there are differences. You may notice that there are no metric-to-metric or metric-to-U.S. standard conversion tables.
